Effects of the density, aviary type, breed, and age on the behaviors of laying hens kept in cages
(2008-12-01)
An experiment was carried out in order to investigate the behaviors of laying hens due to the environmental factors of: density inside of the cage, aviary type, breed, and age. The experiment was configured as a factorial ...
Influence of the environment on behavior patterns of laying hens kept in cages
(2008-12-01)
The aim of this paper is to verify the correlation between environmental indicators and behaviors expressed by laying hens kept in cages. The birds react to a severe environment through their behaviors, end the behaviors ...
Inverter-fed linear asynchronous machine
(1998-12-01)
The behaviors of an arc-shaped stator induction machine (the sector-motor) and a disc-secondary linear induction motor are analyzed in this work for different values of the frequency. Variable frequency is produced by a ...
Sugarcane response to two biotic stressors: Diatraea saccharalis and Mahanarva fimbriolata
(2011-06-01)
In a field experiment in 2007/08 in Sao Paulo state, Brazil cane was exposed to sugarcane borer (Diatraea saccharalis) and spittlebug (Mahanarva fimbriolata) alone or in combination. Plots comprised 2 m2 caged and uncaged ...
Responsible use of resources for sustainable aquaculture
(Food and Agriculture Organization of the United NationsPhuket, 2010-09-22)
Comparisons of production, water and energy efficiencies of aquaculture
versus an array of fisheries and terrestrial agriculture systems show that nonfed
aquaculture (e.g. shellfish, seaweeds) is among the world’s most ...
Gps-Inspired Method For Rodent Tracking Using Arduino-Based Open Field And Fft Analysis
(2014)
Due to the fact that video-based tracking methods for laboratory rats are expensive and time consuming,
a novel approach of the time dependent position was developed. In this work we show a new kind of cage
for performing ...
